    en.wikipedia.org/wiki/Orbit_of_Venus

    Venus was 0.7205 au from the Sun on the day of transit, decidedly less than average. [9] Moving far backwards in time, more than 200,000 years ago Venus sometimes passed by at a distance from Earth of barely less than 38 million km, and will next do that after more than 400,000 years.

    Consequently, Venus transits above Earth only occur when an inferior conjunction takes place during some days of June or December, the time where the orbits of Venus and Earth cross a straight line with the Sun. [185] This results in Venus transiting above Earth in a sequence of currently 8 years, 105.5 years, 8 years and 121.5 years, forming ...

    The first time, it flew by on October 24, 2006, passing 3000 km from Venus. As Earth was on the other side of the Sun, no data was recorded. [ 37 ] The second flyby was on July 6, 2007, where the spacecraft passed only 325 km from the cloudtops.

    His observations allowed him to make a well-informed guess for the diameter of Venus and an estimate of the mean distance between the Earth and the Sun (59.4 million mi (95.6 million km; 0.639 AU)). His observations were not published until 1661, well after Horrocks's death.

    Venus is the second planet from the sun, and Earth the third. ... The Venusian diameter of about 7,500 miles (12,000 km) is just a tad smaller than Earth's 7,900 miles (12,750 km).

    The radius of the Sun is 0.0047 AU (700,000 km; 400,000 mi). [58] Thus, the Sun occupies 0.00001% (1 part in 10 7) of the volume of a sphere with a radius the size of Earth's orbit, whereas Earth's volume is roughly 1 millionth (10 −6) that of the Sun. Jupiter, the largest planet, is 5.2 AU from the Sun and has a radius of 71,000 km (0.00047 ...

    In October 2018, it broke the record of being the closet human-made object to the sun at 26.55 million miles, a record that was originally set by the Helios 2 spacecraft in 1976.
